Both beams seem to have wave/particle duality.
------------------------------------------
If we consider in a simple way the think, a focus electron beam behave somehow like a light beam even if it is a particle beam. Thus diffraction figures can be observed on a screen if the electron beam passes through a very small gap.
The great difference is that the equivalent wavelength of the electron beam seems to be very small with respect to light beam. The observed wavelength of an electron beam depends on electrons energy, being in general of the order of 1 nm (one meter part out of one billion) while green light has a wavelength of the order of 540 nm.
If we look more in deep the phenomenon, in quantum mechanics both a light beam and an electron beam are particle beams, being photons the light particles. They are in any case particle that do not resemble small rigid balls, but having quite exotic properties, like generating interference and, in case of photons, to be at light speed in any possible situation.
The basic difference is that electrons are fermions, with spin equal to 0.5 and a finite rest mass, while photons are bosons, with zero spin and zero rest mass. This difference causes the macroscopic difference in their behaviours.

What are the similarities between a computer mouse and a light-pen?
Both are input devices
What are the similarities between light and gamma rays?
Light ray and gamma ray both travel in a straight line.
What is the relationship between electromagnetic spectrum light and sight?
Anything that can reflect light is only visible to an eye... others which cannot are dark..
What are similarities between leap year and light year?
Both contain the word "year," but are otherwise unrelated. A light year is a unit of distance, while a leap year is a correction to a unit of time.
What is the similarities between the insolation and the terrestrial radiation?
i need to know two different similarities between light and infrared radiation?" this is Jakupi Patriot Baldwin school Pittsburgh 15227 well i only know one- they are both invisible unless they are either reflected or looked at throught something. e.g a camera
What are the similarities between WD 40 and a light bulb?
There are no similarities between WD 40 lubrication oil and a device that produces visible light when a current is applied across its filament load.
What are the similarities between WD-40 and a light bulb?
There are no similarities between WD 40 lubrication oil and a device that produces visible light when a current is applied across its filament load.
What is the electro-magetic spectrum?
gamma rays, xrays, uv light, visible light, infra red, microwaves, radio waves
Is the visible light spectrum between radar waves and xrays?
No, the visible light spectrum falls between infrared and ultraviolet light on the electromagnetic spectrum. Radar waves have longer wavelengths than visible light, while X-rays have shorter wavelengths.
What is the difference between an LED light and a fluorescent light?
It would actually be easier to list the similarities between them: They both convert electricity into visible light. That's pretty much it. Everything else about them is completely different.
Astronomers think that the areas around black holes give off?
A. visible light B. Nebulas C. Helium or D. Xrays
Which type of energy includes visible light xrays and microwaves?
Electromagnetic energy includes visible light, X-rays, and microwaves. These forms of energy are all part of the electromagnetic spectrum, which encompasses a wide range of electromagnetic waves with varying frequencies and wavelengths.
What is the comparison between visible light and ultra violet light?
You can see visible light but not ultra violet light.
Visible light fits between x-rays and uv?
No, the visible light region is between Infra-red and UV.
Which waves have shorter wavelengths radio waves or xrays?
X-rays have shorter wavelengths than radio, heat, infra-red, visible light, and ultra-violet.
What is between visible light and the electromagnetic spectrum?
Visible light is a small section in the electromagnetic spectrum.
Visible light is between which two electromagnetic radiations?
The visible spectrum between red and violet.
